Definitions

  • the first reflective element is disposed exclusively on the first region.
  • the substrate may further comprise a third region, and the reflective feature further comprises a third reflective element disposed on the third region, wherein the third reflective element is more adherent than the first reflective element or the second reflective element to the third region.
  • the first reflective element and the second reflective element optionally form a continuous graphical feature that spans at least a part of the first region and at least a part of the second region.
  • the first region (and the first surface thereof) is more hydrophilic (less hydrophobic) than the second region (and the second surface thereof). In another embodiment, the first region (and the first surface thereof) is less hydrophilic (more hydrophobic) than the second region (and the second surface thereof). In another embodiment, the first region (and the first surface thereof) has a surface energy that is greater than the surface energy of the second region (and the second surface thereof). In another aspect, the first region (and the first surface thereof) has a surface energy that is less than the surface energy of the second region (and the second surface thereof).
  • the first reflective or non-reflective element (as well as the first ink used to form the first element) is disposed exclusively on the first region.
  • the second reflective or non-reflective element is optionally more adherent than the first reflective element to the second region, this example minimizes the potential for beading, smearing, over-saturation and/or overall poor adhesion that would likely occur if the first element (or a portion thereof) was formed on the second region. Forming the first element exclusively on the first region, therefore, contributes to the desired reflectivity and/or appearance of the overall reflective or non-reflective feature.
  • the reflective or non-reflective feature comprises a substrate having a first region comprising a first undercoat.
  • the first undercoat optionally comprises a composition selected from the group consisting of varnishes, offset varnishes, dry offset varnishes, shellacs, latexes, and polymers.
  • the term "undercoat” refers to a coating disposed underneath a reflective or non-reflective element and on top of a supporting substrate. If the first region comprises a first undercoat, the first reflective element (in those aspects in which the first element is reflective), which is disposed on the first undercoat of the first region, exhibits enhanced reflectivity relative to the reflectivity of the first reflective element in the absence of the first undercoat. The presence of the undercoat may also facilitate adhesion and durability of the first reflective or non-reflective element.
  • the step of forming the reflective or non-reflective element comprises depositing a second ink onto the second surface and treating the deposited second ink under conditions effective to form the reflective or non-reflective element.
  • the composition and properties of the second ink may be as described above with reference to the inks used to form the reflective or non-reflective elements of the other features of the present invention.
  • the depositing comprises direct write printing, e.g., a piezo-electric, thermal, drop-on-demand or continuous ink jet printing, the second ink onto the second surface.
  • the treating comprises allowing the second ink to dry, heating the deposited second ink and/or applying UV radiation to the deposited second ink.
  • the treating comprises applying UV radiation to the deposited second ink.
  • the substrate comprised (uncoated) glossy Epson photopaper.
